    Abstract

    Electrodeposition of polypyrrole (PPy) in supercritical carbon dioxide (scCO2) emulsified electrolytes containing anionic surfactant sodium dodecyl sulfate (SDS) has been reported. By changing SDS concentration and the CO2/water volume ratio, PPy films with different morphologies, such as nodular, granular, and flower-like structures, are fabricated. The PPy films prepared in the scCO2 emulsified electrolytes show better redox properties than PPy films prepared in an aqueous electrolyte. Moreover, their redox properties are found to be affected by their respective morphologies.

    Necking and barreling deformation behaviors occurred simultaneously during the bending test of a single-crystal gold micro-cantilever (sample A) with the loading direction parallel to the [1-10] orientation and the neutral plane parallel to the [110] orientation. In contrast, for another single-crystal gold micro-cantilever, sample B, with the loading direction aligned parallel to the [0.37 −0.92 0.05] orientation and the neutral plane parallel to the [0.54 0.28 0.78] orientation, predominant slip band deformation was noted. Sample A exhibited activation of four slip systems, whereas sample B demonstrated activity in only a single-slip system. This difference suggests that the presence of multiple slip systems contributes to the concurrent occurrence of necking and barreling deformations. Furthermore, variations in the thickness of the micro-cantilevers resulted in observable strengthening, indicating that the effect of sample size is intricately linked to the geometry of the cross-section, which we have termed the “sample geometry effect”.

    Ni–W alloys have received considerable interest as a promising structural material for microelectromechanical systems (MEMS) due to their exceptional properties, including hardness, ductility, corrosion resistance, and thermal stability. However, the electrodeposition of Ni–W alloys in the MEMS fabrication process to achieve intact structures with a thickness of several tens of micrometers is challenging due to the occurrence of cracking caused by side reactions and internal stresses during the electrodeposition process. To address this issue, our focus was on pulsed reverse electrodeposition (PRE) as a potential solution. The utilization of the PRE technique allows for a high concentration of reactive species on the electrode surface, thereby mitigating side reactions such as hydrogen generation. In this study, we examined the effects of the PRE method on the morphological characteristics, average crystal grain size, Vickers hardness, and micro-mechanical properties of Ni–W alloys.

    Abstract

    Structural engineering has proven effective in tailoring the photocatalytic properties of semiconductor nanostructures. In this work, a sophisticated double‐hollow yolk@shell nanostructure composed of a plasmonic, mobile, hollow Au nanosphere (HGN) yolk and a permeable, hollow CdS shell is proposed to achieve remarkable solar hydrogen production. The shell thickness of HGN@CdS is finely adjusted from 7.7, 18.4 to 24.5 nm to investigate its influence on the photocatalytic performance. Compared with pure HGN, pure CdS, a physical mixture of HGN and CdS, and a counterpart single‐hollow cit‐Au@CdS yolk@shell nanostructure, HGN@CdS exhibits superior hydrogen production under visible light illumination (λ = 400–700 nm). The apparent quantum yield of hydrogen production reaches 8.2% at 320 nm, 6.2% at 420 nm, and 4.4% at 660 nm. The plasmon‐enhanced activity at 660 nm is exceptional, surpassing the plasmon‐induced photoactivities of the state‐of‐the‐art plasmonic photocatalysts ever reported. The superiority of HGN@CdS originates from the creation of charge separation state at HGN/CdS heterojunction, the considerably long‐lived hot electrons of plasmonic HGN, the magnified electric field, and the advantageous features of double‐hollow yolk@shell nanostructures. The findings can provide a guideline for the rational design of versatile double‐hollow yolk@shell nanostructures for widespread photocatalytic applications.

    This study reports on the use of supercritical CO2 (scCO2) for the metallization of ultrahigh-molecular-weight polyethylene (UHMW-PE) filaments, which are used as functional components in weavable devices. UHMW-PE is well known for its chemical and impact resistance, making it suitable for use in bulletproof clothing and shields. However, its chemical resistance poses a challenge for metallization. By utilizing scCO2 as the solvent in the catalyzation process, a uniform and defect-free layer of Ni-P is successfully deposited on the UHMW-PE filaments. The deposition rate of Ni-P is enhanced at higher temperatures during the scCO2 catalyzation. Importantly, the durability of the Ni-P-metalized UHMW-PE filaments is improved when the scCO2 catalyzation is carried out at 120 °C, as evidenced by minimal changes in electrical resistivity after a rolling test.

    Density‐functional theory (DFT) is pivotal in the advancement of photocatalysis and photoelectrocatalysis. Its capability to explore electronic structures of materials contributes significantly to clarifying the mechanisms of photocatalytic (PC) and photoelectrocatalytic (PEC) processes. DFT calculations enable a deeper understanding of how these processes work at a molecular level, which is essential for designing versatile photocatalysts and photoelectrodes and optimizing reaction pathways. In this perspective, key PC and PEC applications, such as H2 production, CO2 reduction, dye degradation, and N2 reduction, where DFT is instrumental in optimizing materials designs and reaction pathways, are highlighted. Exploration on the synergy between experimental research and DFT calculations is highlighted, which is crucial for the development of efficient and environmentally friendly energy solutions. The discussion further extends to challenges and future directions, emphasizing the need for incorporating factors, including discrepancy in scale, light illumination, electrolyte presence, and applied bias, into DFT calculations, to achieve a more comprehensive understanding of PC and PEC systems. In this perspective, it is aimed to provide a holistic view of the current state and potential advancements in photocatalyst and photoelectrode modeling, thereby guiding future research toward more effective and sustainable energy and chemical production processes in PC and PEC systems.

    Alloy electrodeposition of Ni-Co alloys is known to show an anomalous codeposition behavior, which the concentration of cobalt in the deposited alloy is higher than the concentration of cobalt ions in the electrolyte. In this study, the cobalt content in the alloy is increased from 30 at% to 60 at% through introduction of bromide ions into a sulfamate bath, while addition of chloride ions does not give any significant influences to the alloy. The bromide ions are found to promote the reduction of cobalt ions but inhibit the reduction of nickel ions. Effects of the pH are also investigated to provide possible explanation to the phenomenon observed, and the anomalous codeposition behavior becomes more obvious in a more acidic electrolyte.

    Polyethylene terephthalate (PET) is known to be highly inert, and this makes it difficult to be metallized. In addition, Pt electroless plating is rarely reported in the metallization of polymers. In this study, the metallization of biocompatible Pt metal is realized by supercritical CO2 (sc-CO2)-assisted electroless plating. The catalyst precursor used in the sc-CO2 catalyzation step is an organometallic compound, palladium (II) acetylacetonate (Pd(acac)2). The electrical resistance is evaluated, and a tape adhesion test is utilized to demonstrate intactness of the Pt layer on the PET film. The electrical resistance of the Pt/PET with 60 min of the Pt deposition time remains at a low level of 1.09 Ω after the adhesion test, revealing positive effects of the sc-CO2 catalyzation step. A tensile test is conducted to evaluate the mechanical strength of the Pt/PET. In-situ electrical resistances of the specimen are monitored during the tensile test. The fracture strength is determined from the stress value when the short circuit occurred. The fracture strength is 33.9 MPa for a specimen with 30 min of the Pt deposition time. As the Pt deposition time increases to 45 min and 60 min, the fracture strengths reach 52.3 MPa and 65.9 MPa, respectively. The promoted fracture strength and the decent electrical conductivity demonstrate the advantages toward biomedical devices.

    Abstract

    Ni-B alloy films are prepared by electrodeposition with a Watt’s bath-based electrolyte. The B content decreases from 14.3 at.% to 2.8 at.% as the current density increases from 1 A/dm2 to 4 A/dm2. For applications in miniaturized electronics, the micro-scale mechanical property is evaluated by micro-compression test using micro-pillar type specimens. As-deposited Ni-B alloy films exhibit high mechanical strengths and ductility. The Ni-B alloy films are heat treated to evaluate the thermal stability. After the heat treatment, strengthening and formation of an intermetallic compound, Ni3B, are confirmed. The deformation behavior of the micro-pillars changes from ductile to brittle after the 250 °C heat treatment, and the compressive strength of the Ni-B alloy film having the B content of 2.8 at.% reaches 5.67 GPa due to the precipitation strengthening mechanism by the Ni3B.

    A comprehensive review of the electroactive materials for non-enzymatic glucose sensing and sensing devices has been performed in this work. A general introduction for glucose sensing, a facile electrochemical technique for glucose detection, and explanations of fundamental mechanisms for the electro-oxidation of glucose via the electrochemical technique are conducted. The glucose sensing materials are classified into five major systems: (1) mono-metallic materials, (2) bi-metallic materials, (3) metallic-oxide compounds, (4) metallic-hydroxide materials, and (5) metal-metal derivatives. The performances of various systems within this decade have been compared and explained in terms of sensitivity, linear regime, the limit of detection (LOD), and detection potentials. Some promising materials and practicable methodologies for the further developments of glucose sensors have been proposed. Firstly, the atomic deposition of alloys is expected to enhance the selectivity, which is considered to be lacking in non-enzymatic glucose sensing. Secondly, by using the modification of the hydrophilicity of the metallic-oxides, a promoted current response from the electro-oxidation of glucose is expected. Lastly, by taking the advantage of the redistribution phenomenon of the oxide particles, the usage of the noble metals is foreseen to be reduced.

    Strengthening of electrodeposited Au-based materials is achieved by co-electrodeposition with TiO2 nanoparticles dispersed in a sulfide-based gold electrolyte. TiO2 content in the composite film is adjusted by concentration of the TiO2 in the gold electrolyte. Effects of the TiO2 content on surface morphology, crystalline structure and microstructure of the composite film are investigated. Mechanical properties of the Au–TiO2 composite films are evaluated by micro-Vickers hardness and micro-compression tests. The hardness increases from 135 to 207 HV when the TiO2 content is increased from 0 to 2.72 wt%. Specimens used in the micro-compression test are micro-pillars fabricated from the composite film, and the yield strength reaches 0.84 GPa by incorporating 2.72 wt% TiO2 into the film.

    Atomic-level gold clusters are decorated on a polyaniline (PANI) support by a cyclic atomic electrodeposition process, and the catalytic activity in the oxidation of glucose is studied. The evaluation is conducted by cyclic voltammetry using atomic-level gold clusters-decorated PANI (PANI/AuN, where N indicates the atomic size of the Au cluster and N = 1~3 in this study) as the working electrode and a solution containing 0 to 50.0 mM of glucose in phosphate-buffered saline. The catalytic activity is determined from the oxidation current observed at around +0.6 V vs. Ag/AgCl. The catalytic activity is found to be affected by the size of gold clusters decorated on the PANI/AuN, whereby the catalytic activity is low when N is 1 or 3. On the other hand, an obvious enhancement in the catalytic activity is observed for the PANI/Au2 electrode.

    次世代インテリジェントテキスタイルを実現するために、超臨界二酸化炭素を用いた触媒化技術によるフレキシブルセンサー用触媒電極としてのPETフィルムの機能化が実現した。また、白金は生体適合性のある金属だが、ポリマー材料の白金メタライゼーションは難しいことが知られている。超臨界二酸化炭素を用いた触媒化技術により、PETと白金の統合が実現された。この白金被覆したPETフィルムについて、SEM観察により表面の状態を明らかにし、さらに高次構造解析を固体NMR法により詳細に行うことにより、触媒化とめっき処理による構造変化に関する知見を得た。また、センシング、光触媒による抗菌・抗ウイルス性、および身体情報提示の各機能を有するインテリジェントウェアラブル材料の基布となる各繊維を用いて、全反射測定法によるフーリエ変換赤外吸収スペクトル測定などにより、比較のための材料表面情報を得た。また各機能性ウェアラブル材料の安全性評価のための予備検討を進めた。
    導電性に優れたスマートテキスタイルを情報処理技術と組み合わせることで、日々の暮らしを見守ったり日常生活を豊かにするインタフェースとして構築する研究に取り組んだ。特に、乳がん患者支援や水難事故防止といった、問題解決が困難な事象にもスマートテキスタイルを用いたシステムが役立つ事を示した。また、その成果を生かし、技術の国際標準化や啓蒙活動にも貢献することができた。
    導電性繊維のウェアラブルヒータとしての応用にむけ、温度勾配のある面的な刺激の有効性を評価し、一様な刺激よりも効率良く温感を提示しうることが示唆された。また、筋電気刺激用ウェアラブル電極としての応用に向け、姿勢維持の補助デバイスとしての効果を確認した。さらにに、月経痛の再現デバイスとして、実際の月経痛よりも腹部の浅い位置ではあるが同等の強度を提示しうることを確認した。

    次世代インテリジェントテキスタイルを実現するために、撚り数の異なるPETおよびナイロン繊維(ヤーン)を準備し、超臨界CO2触媒化手法を用いて、ニッケルリンめっきを試みた。この結果、撚り数の増加と共に、金属被覆が向上することを見出した。光学顕微鏡による金属被覆性および電気伝導性を計測し、双方が明確に向上することが明らかになった。繊維(ヤーン)一本で金属化することは困難であるが、本研究により実現できた。
    これらのめっき繊維の表面の状態をSEM観察により明らかにし、さらに高次構造解析を固体NMR法により詳細に行うことにより、触媒化とめっき処理による構造変化に関する知見を得た。
    さらに応用研究としてスマートテキスタイルを用いて、1:基礎体温計測可能な下着や腹囲計測ベルトのような健康管理への応用、2:海中転落事故救助ライフベストやスマート防災服のような安全管理への応用、3:その他、エンターテインメント等への応用、の3つのカテゴリにおいて、従来実現できなかった機能を備えたシステムの提案・開発・評価に取り組んだ。また、導電性繊維をEMS(電気筋肉刺激)装置に応用する一例として、背中へのEMSで適切な座位姿勢の維持を支援するウェアラブルシステムを検討した。本年は特に、導電性繊維の配置位置の設計に向け、EMSの部位による効果の差、および長期的な効果について評価した。結果として、肩部よりも腰部に対するEMSが有効であること、および長期的な姿勢維持効果が示された。

    We have successfully realized void free plating of Pt on silk fiber by using supercritical carbon dioxide and moreover electrochemical deposition of high functional inorganic oxide such as titanium oxide on the metal-plated fiber. Solid-state NMR measurements of these fibers provided information on the higher-order structural changes due to plating, which can be fed back for further functional improvements.
    As an application of these intelligent fibers, we have been working on the development of sensing wear that can visualize heart rate, respiration, and exercise using smart textiles. We also showed the feasibility of health monitoring during sleep, which can store human information measured by sensing wear as big data in the cloud and detect abnormalities using statistical analysis. In addition, we showed the conditions for thermal stimulation that enhances comfort. We also showed the applicability to support for the visually impaired and communication support via stuffed animals.
